Preparation and characterization of lanthanum palygorskite clays as acid catalysts
Palygorskite clays containing 2, 4, 6 or 10% lanthanum (w/w) were prepared by ion-exchange from acid-leached natural clays. Samples were characterized by chemical and thermogravimetric analysis, X-ray diffraction, infrared spectroscopy, and N2 adsorption. Isopropyl alcohol was transformed in order t...
